y .1 My invention IS an lmprovement 1n couches, and the inventionhas for its object to provide a device of the character specified, wherein the couch is so mounted and arranged that it may be used as a vibrator of the couch,Fig. 2 isa top plan view with 0 for the treatment of certain affections of the 7 system, the couch comprising a body ofthe usual construction and a mounting for imparting a series of rapidly succeeding vlbrations to the body.

V In the drawings: Figure 1 is a front view.

'parts broken away to show the mounting,

In the present embodiment of the invention, a couch body is provided, the said body comprising a framel of rectangular form and of usual construction, having at the upper surface thereof a padded upholstered cushioned surface 2, connected to the body in the usual manner and supported by springs.

The body is provided with a pair of depending pedestals- 3 at each end, the members of each pair being in register transversely of the frame, and each pedestal is provided with a pair of bearings 4, the said bearings bein at, the ends of the pedestal, and the bearings of this pedestal register with those of the pedestal at the opposite side of the frame. Afshaft. 5 is journaled in each pair of registering bearings, and each shaft is provided withv wheels 6 near its ends. The wheels 6' are arranged between the bear.- ings 4 and a collar 7 mounted on the shaft 5 and held in adjusted position by means of a set'screw -8. pair of bearing standards 9 is arranged at each "end of the couch, and each standard is provided with a sectional bearing 10. The bearings 10 of the standards at each end of the couch are in register or-alinement, and shafts 12 and 13'are jour-- naled in the registering bearings at each end of the couch. A roller 14; is secured toeach shaft between the bearing standards and each ofthe. said rollers hasits" periphz;

eral surfaces longitudinallygrooved or cor,-

rugated as shown in the drawing. One/of-- t'he shafts 12, in the presentinstance, ispro--.

vided with a pulley 15 at one end, the said end of the shaftv being extended beyond the bearing 10,'and by means o f'the pulley the adjacent shaft 12 may be connected with a suitable source of power to rotate therollers.

The wheels 4 of each pedestal engage the peripheral surface of the adjacent roller, and the said wheels are spaced apart a sulfi- .cient distan ce to permit the wheels to engage the rollers the manner shown in Fig. '1. Since the wheels 6 engage the corrugated or roughened rollers directly it will be evident that when the saidrollers'are rotated in either direction a series of rapidly succeeding vibrations or jars will be imparted .to the wheels and to the couch. The members of each p,air" ofwheels 6'of wpedestztl ever, provided for preventing this riding v motion, and to hold the couch body in central positlon. The said mechanism; comprises angle plates 16 secured to each corner of the couch frame, and each angle plate has .an eye 17 at' its lower end.

A" link 18 is arranged at each corner of the couch, each of the said links having eyes 19 at its opposite ends. iOne of the eyes 19,

of each link engages the eye 17 ofan angle plate, and the other e e of the. link engages an eye 20 secured to t e supporting surfaces for the'standards .9. Each link extends o twardly and downwardly away from the it ja'eent corner of the couch as clearly shown,

and acoil spring 21 is interposed in the H length of each link. This spring 21 may be integral with'the link if desired, or the link may be sectional and the ends of the link may be connected to the spring. When the rollers 14 are rotated a series of successive shocks or jars will be imparted to the-couch 12, and the patient to be treated will recline. upon the couch during this'treatment. Thus a series of rapidly succeeding vibra tions will be imparted to the patient, and' this may continue so long as the rollers are rotated. The rapidity accordance with the conditions of the patient to be treated. The links and springs hold I of the vibration imparted to 1 the couch will depend upon the speed of ro-.

ta'tion' of the rollers 14, and this speed may .be varied from slow to exceedingly rapid in the couch .in central position, and in the proper relative position with respect to the rollers.

1. A couch, comprising a body, a pair of transversely alined standards at each end ofthe body, a roller journaled in each pair of standards, each roller having its peripheral surface corrugated 0r grooved longitudinally of the roller, a pair of pedestals connected with the couch body at each end thereof and in alinement transverse to the body, a pair of shafts journaled in the pedestals at each end of the body and parallel with each other, wheels'secured to each shaft near the ends thereof and engaging the roughened surface of the adjacent roller, the shafts being spaced apart a distance'corresponding approximately to the diameter of the roller, and yielding mechanism for normally holding the couchin central position, said means comprising links pivoted to the cornersof the couch body and-extending outwardly and downwardly therefrom to a connectlon with the supporting surface for the standards, and a spring interposed in the length of each link. i

2. A couch, comprising a body, a pair of transversely alined standards at each end of the body, a roller journaled in each pair of standards, each roller having its periph-, eral surface corrugated or rooved longitudinally of the roller, a palr of pedestals estals at each end of the body and parallel with each other, wheels secured to each shaft near the ends thereof and engaging the roughened surface of the adjacent 'roller, the shafts being spaced apart a distance corresponding approximately to the diameter ofthe roller, and yielding mechanism for normally holding the couch in central position.

L 3. A couch, comprising a body, a roller "having a roughenedperipheral surface journaled transversely beneath the couch at each end thereof, wheels on the couch and restingon the rollers, and links connected with each corner of the couch and extending out wardly therefrom toa connection, with a fixed su port, said links being resilient to I permit t e couch to yield.

. 4. A couch, comprising a body, a roller having a roughened peripheral surface'journaled transversely beneath the couch at each end thereof, wheels on the couch and resting on the rollers, and yielding means connected with the couch for normally holding the couch in position with respect to the rollers.
